Detergent compositions

Abstract

Alkaline built detergent bleach compositions are disclosed comprising a surface-active agent; a peroxide compound bleach; a manganese compound which delivers manganese (II) ions in aqueous solution (e.g. manganous sulphate or manganous chloride); and a builder mixture comprising a water-insoluble aluminosilicate ion-exchange material and an alkalimetal orthophosphate and/or an alkalimetal silicate. The composition is particularly effective for washing fabrics at lower temperatures, e.g. from 20 DEG to 60 DEG C., but is also usable at higher temperatures.

I claim: 
     
       1. A build detergent bleach composition comprising from 2 to 50% by weight of a surface-active agent selected from the group consisting of organic anionic, nonionic, amphoteric and zwitterionic detergents and mixtures thereof; 4-50% by weight of a peroxide compound bleach; 10-50% by weight of a water-insoluble aluminosilicate cation-exchange material; 3-50% by weight of an alkali-metal orthophosphate; 0-20% by weight of an alkalimetal silicate; and a manganese compound which delivers manganese(II) ions in aqueous solution, in an amount of from 0.005 to 2.5% by weight as manganese (II) metal based on the total detergent composition. 
     
     
       2. A built detergent bleach composition comprising from 2 to 50% by weight of a surface-active agent selected from the group consisting of organic anionic, nonionic, amphoteric and zwitterionic detergents and mixtures thereof; 4-50% by weight of a peroxide compound bleach; 10-50% by weight of a water-insoluble aluminosilicate cation-exchange material; 0-50% by weight of an alkali-metal orthophosphate; 1-20% by weight of an alkalimetal silicate; and a manganese compound which delivers manganese(II) ions in aqueous solution, in an amount of from 0.005 to 2.5% by weight as manganese (II) metal based on the total detergent composition. 
     
     
       3. A composition according to claim 1, wherein said manganese compound is a manganese (II) salt selected from manganous sulphate and manganous chloride. 
     
     
       4. A composition according to claim 2, wherein said manganese compound is a manganese (II) salt selected from manganous sulphate and manganous chloride. 
     
     
       5. A composition according to claim 1, which contains from 0.025 to 1.0% by weight of manganese (II) metal. 
     
     
       6. A composition according to claim 2, which contains from 0.025 to 1.0% by weight of manganese (II) metal.
